HI all, i am vignesh, i am just begin with RF, i am using SX1212, in that i am facing problem in VCO ,PLL lock detection, it always shown me that PLL is not locked. pls any one suggest me how to solve the problem and also i searched in many website, there is no much information on sx1212. kinldy help me.

Hi Vignesh: I stopped supporting SX1212 because the driver is very difficult. The PLL Lock signal from the chip doesn't work. You need to time each stage of the startup process according to the datasheet.

Or, just use another chip. If you like semtech, maybe the LoRa parts are OK for you.
